The METRx Micro Endoscopic Discectomy involves inserting a needle, guided by low-dose X-ray, to the level of the herniated disc. Once the disc level is precisely located, the needle is removed and a 16-18mm incision is made. Dilating tubes, increasing in size, are then passed through the incision to displace—not cut—the muscles, creating a small "tunnel" that the surgeon can use to access the herniated disk and remove the herniated portion pressing on the nerve. At the end of the procedure, when the working tube is removed, the displaced muscle falls back into its natural location. Displacing the muscles instead of cutting through them to access the herniated disc eliminates surgical trauma to the muscle and dramatically reduces recovery time. The entire procedure generally takes about 1-1/2 hours.
